Description

Technical Field

[0001] This invention relates to the field of sensor devices, and more specifically to a piezoelectric non-destructive monitoring sensor. Background Technology

[0002] Non-destructive testing (NDT) is a technique used to assess the integrity and performance of materials, components, or systems without impairing their future use. Traditional NDT methods include ultrasonic testing, radiographic testing, and magnetic particle testing. NDT is a type of monitoring technology that does not require damage or significant alteration to the component being tested during the monitoring of defects in materials and products. The purpose of this type of monitoring is typically to determine the location and size of defects such as cracks, voids, delamination, peeling, residual stress, poor fit, dimensional inaccuracies, and material inhomogeneity. NDT technology, to a certain extent, reflects a country's level of industrial development, and its importance is widely recognized. In November 1978, my country established the Non-Destructive Testing Branch of the Chinese Mechanical Engineering Society. Subsequently, various NDT societies or associations were established in different industries and regions, and some universities offered NDT courses, promoting basic theoretical research and instrument development in NDT, and driving the application of NDT technology. The rapid development of NDT technology has led to the formation of a series of monitoring methods.

[0003] Some non-destructive testing methods require point-by-point scanning, resulting in slow monitoring speeds and unsuitability for large-scale rapid monitoring. X-ray monitoring, for example, is expensive due to high equipment costs and the need for specialized personnel, increasing monitoring costs. Certain monitoring methods require complex equipment and specialized knowledge, hindering rapid on-site and real-time monitoring. Existing document 201910630717.7 states that methods such as X-ray monitoring pose radiation safety risks, requiring strict safety measures. Some monitoring methods are only applicable to specific materials or structures, limiting their ability to monitor complex structures. Therefore, this invention proposes a piezoelectric non-destructive testing sensor to address the problems existing in the prior art. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a piezoelectric non-destructive testing sensor. This sensor is an improvement upon existing piezoelectric sensors, offering immediate use, wireless transmission, and independence from network limitations. It can connect to various platforms and networks, features built-in positioning capabilities, and is easy, fast, and efficient in maintenance, saving labor costs. In practical use, the cable is passed through the movable opening below the upper pressure seat, driving a small cylinder to lower the upper pressure seat, thereby achieving the purpose of clamping the cable with a fixing plate. Friction buffering is provided during installation when tension occurs, facilitating the monitoring of wires and cables. A defect detection box on one side utilizes an ultrasonic detector to inspect parts or wires, enabling timely detection of damaged or aged parts.

[0005] The technical solution of this invention is implemented as follows: A piezoelectric non-destructive testing sensor includes a sensor body, a monitoring component, and an internal component assembly. The monitoring component is fixedly installed on the top of the sensor body, and the internal component assembly is fixedly installed inside the sensor body.

The monitoring component includes a mounting base, a current detection port, an upper pressure seat, a movable port, a small cylinder, a defect detection box, and an ultrasonic detector. The mounting base is fixedly installed on the top of the sensor body. Multiple sets of current detection ports are opened on the inner side of the mounting base. Each set of current detection ports has the same size and specifications. An upper pressure seat is movably installed on one side of the current detection port. Multiple sets of movable ports are opened below the upper pressure seat. Small cylinders are fixedly installed on both sides of the upper pressure seat. The output end of the small cylinder is connected to the upper pressure seat. A defect detection box is installed on one side of the top of the mounting base, and an ultrasonic detector is fixedly installed on the top of the defect detection box.

[0006] A further improvement is that the internal component assembly includes a built-in sensor, a piezoelectric element, a chip body, wires, and an insulating ceramic base. The built-in sensor is fixedly mounted on the sensor body, and a piezoelectric element is fixedly mounted below the built-in sensor. The chip body is fixedly mounted inside the built-in sensor, and a wire is fixedly connected to one side of the chip body. Insulating ceramic bases are fixedly mounted on both sides inside the built-in sensor.

[0007] A further improvement is that a pull-out plate is movably installed on one side of the sensor body, a solar panel is fixedly installed inside the pull-out plate, a storage battery is fixedly installed inside the sensor body, and the solar panel and the storage battery are electrically connected to each other.

[0008] A further improvement is that: the bottom of the upper pressure seat is provided with multiple sets of lower pressure ports, and multiple sets of insulating rubber pads are fixedly installed on the inner side of the lower pressure ports; a back plate is fixedly installed on one side of the sensor body, and mounting seats are fixedly installed on both sides of the back plate.

[0009] A further improvement is made in that: a current display is fixedly installed on the front of the back plate, the current display is electrically connected to the current detection port, a defect display screen is fixedly installed on one side of the current display, and the defect display screen is electrically connected to the defect detection box.

[0010] A further improvement is made in that a red indicator light is fixedly installed above the back panel, and a green indicator light is fixedly installed on one side of the red indicator light.

[0011] A further improvement is that a winding bracket is fixedly installed on one side of the top of the sensor body, a winding roller is rotatably installed inside the winding bracket, a winding motor is fixedly installed on the outside of the winding bracket, and the output end of the winding motor is connected to the winding roller.

[0012] A further improvement is that a correction seat is fixedly installed on one side of the top of the sensor body, and a correction sleeve is rotatably installed on the top of the correction seat.

[0013] A further improvement is that a movable cover plate is fixedly installed on one side of the top of the sensor body, and a mounting buckle is fixedly installed on one side of the movable cover plate.

[0014] A further improvement is that a charging port is fixedly installed on the front of the sensor body.

[0015] Compared with existing technologies, this invention has the following advantages: This sensor, through the coordinated use of a mounting base, current detection port, upper pressure seat, movable port, small cylinder, defect detection box, and ultrasonic detector, is an improvement on existing piezoelectric sensors. It is ready to use immediately upon installation, provides wireless transmission, is not limited by networking, can access various platforms and networks, has built-in positioning function, is easy to maintain, fast and effective, and saves labor costs. In actual use, the cable is passed through the movable port below the upper pressure seat, driving the small cylinder to lower the upper pressure seat, thereby achieving the purpose of fixing the plate to clamp the cable. Friction buffering is provided during installation when pulling occurs, facilitating the monitoring of wires and cables. The defect detection box on one side uses an ultrasonic detector to detect parts or wires, allowing for timely detection and replacement of damaged or aging parts. Real-time... Monitoring and rapid response enable continuous monitoring of structural health, improving detection efficiency. Utilizing the high sensitivity and wide frequency response of piezoelectric sensors, minute vibration signals are captured, enhancing detection accuracy. No physical contact or structural alteration of the monitored object is required, maintaining its original function and performance. Compared to traditional non-destructive testing methods, piezoelectric sensors may have lower equipment and operating costs, avoiding the radiation risks associated with methods like X-ray inspection, ensuring the safety of operators and the surrounding environment. A user-friendly interface and automated data processing flow reduce operator workload. The integrated circuit chip amplifies the weak signal from the piezoelectric pressure sensor and converts its high-impedance input to a low-impedance output. Placing the piezoelectric element at the bottom avoids sensor failure caused by plasma in the measurement environment. Attached Figure Description
